EUA derrubam drone iraniano no Estreito de Ormuz
Os Estados Unidos derrubaram [...] um avião não tripulado iraniano no Estreito de Ormuz, no momento em que ele se aproximava de um navio americano, informou o presidente Donald Trump.
[...] A derrubada da aeronave ocorre em um momento de tensões crescentes na região do Golfo entre os Estados Unidos e o Irã.
[...] A tensão entre Teerã e Washington tem crescido desde que Trump se retirou unilateralmente do acordo nuclear de 2015 com o Irã e voltou a aplicar sanções à República Islâmica.
As hostilidades aumentaram após o Irã derrubar, no dia 20 de junho, um drone americano nas sensíveis águas do Golfo, em meio a uma série de ataques contra petroleiros que Washington atribuiu a Teerã.
A respeito do Estreito de Ormuz e dos conflitos relacionados a ele, considere
as seguintes proposições:
I. O Estreito de Ormuz faz parte de uma das principais rotas mundiais de comércio de petróleo; por isso, qualquer instabilidade político-militar na área onde ele se encontra pode influenciar no preço da gasolina e, consequentemente, na economia de grande parte do mundo.
II. Os Estados Unidos defendem a existência de uma coalizão militar internacional para proteger as águas do Estreito de Ormuz, garantindo a liberdade de navegação na região onde ele se encontra.
III. Apesar das constantes ameaças do Irã, que reivindica o controle do Estreito de Ormuz, em parceria com os Emirados Árabes Unidos, nenhum navio petroleiro foi atacado em suas proximidades (nem mesmo em águas internacionais do Golfo de Omã), o que contribuiu para a estabilidade do preço do petróleo nos últimos cinco anos.

They rose up like men. We saw them. Like men they stood.
We shouldn’t have been anywhere near that place. Like most farmland outside Lotus, Georgia, this here one had plenty scary warning signs. The threats hung from wire mesh fences with wooden stakes every fifty or so feet. But when we saw a crawl space that some animal had dug—a coyote maybe, or a coon dog—we couldn’t resist. Just kids we were. The grass was shoulder high for her and waist high for me so, looking out for snakes, we crawled through it on our bellies. The reward was worth the harm grass juice and clouds of gnats did to our eyes, because there right in front of us, about fifty yards off, they stood like men. Their raised hooves crashing and striking, their manes tossing back from wild white eyes. They bit each other like dogs but when they stood, reared up on their hind legs, their forelegs around the withers of the other, we held our breath in wonder. One was rust-colored, the other deep black, both sunny with sweat. The neighs were not as frightening as the silence following a kick of hind legs into the lifted lips of the opponent. Nearby, colts and mares, indifferent, nibbled grass or looked away. Then it stopped. The rust-colored one dropped his head and pawed the ground while the winner loped off in an arc, nudging the mares before him.
As we elbowed back through the grass looking for the dug-out place, avoiding the line of parked trucks beyond, we lost our way. Although it took forever to re-sight the fence, neither of us panicked until we heard voices, urgent but low. I grabbed her arm and put a finger to my lips. Never lifting our heads, just peeping through the grass, we saw them pull a body from a wheelbarrow and throw it into a hole already waiting. One foot stuck up over the edge and quivered, as though it could get out, as though with a little effort it could break through the dirt being shoveled in. We could not see the faces of the men doing the burying, only their trousers; but we saw the edge of a spade drive the jerking foot down to join the rest of itself. When she saw that black foot with its creamy pink and mud-streaked sole being whacked into the grave, her whole body began to shake. I hugged her shoulders tight and tried to pull her trembling into my own bones because, as a brother four years older, I thought I could handle it. The men were long gone and the moon was a cantaloupe by the time we felt safe enough to disturb even one blade of grass and move on our stomachs, searching for the scooped-out part under the fence. When we got home we expected to be whipped or at least scolded for staying out so late, but the grown-ups did not notice us. Some disturbance had their attention.
Since you’re set on telling my story, whatever you think and whatever you write down, know this: I really forgot about the burial. I only remembered the horses. They were so beautiful. So brutal. And they stood like men.
